Diffusion-Free Dynamics in Rotating Spherical Shell Convection Driven By Internal Heating and Cooling
Neil T. Lewis, Tom Joshi-Hartley, Steven M. Tobias +2
The bulk properties of convection in stellar and giant planet interiors are often assumed to be independent of the molecular diffusivities, which are very small. By contrast, simul…

Heat Transport and Dissipation in 2.5D Rotating Internally Heated and Cooled Convection
Tom Joshi-Hartley, Matthew K. Browning, Laura K. Currie +3
Models of astrophysical convection, such as mixing length theory, typically assume that the heat transport is independent of microphysical diffusivities. Such 'diffusion-free' beha…
